Supervisory
systems have revolutionised the industrial automation scenario all
over the world. In India, what ails the Industrial automation sector
is the shortage of appropriately trained engineers for specialised
jobs in automation. The Faculty of Technology, Jamia Millia Islamia,
has exploited the unlimited job-oriented training potential in the
automation sector, to set up a state-of-the- art center for SCADA
research and training, in the Department of Electrical Engineering.
Special emphasis is being given to Power System automation, as this
has tremendous job potential. This laboratory is primarily used
for Training & Research, as such facilities are presently not
available at any major academic institution in the country. Modular
and customized training programmes are available in this training
center to suit the needs of a variety of automation customers and
for engineering students.
Potential
In
India, there has been significant rise in the level of automation,
as more and more process industries like steel, cement, food
processing, petro-chemicals, refineries, electronic industries etc.
are getting automated. In Power Systems also, SCADA has widespread
application in generation, transmission, distribution and substation
automation. Interestingly, till now, SCADA research and training has
been the propriety of a few leading industrial houses in automation.
The setting up of this state-of-the-art SCADA lab at Jamia Millia
Islamia, for the first time in an academic institution in India,
attains major significance. Now, working engineers in the industry
and students can get full fledged training in SCADA systems here.
This prestigious laboratory has been set up with the help of ABB,
the world leaders in Industrial Automation.
The
Hardware
The
system being set up is a DCS based system,
working on a 32 bit RISC based processor with 4 MB memory (ABB AC
800F Premium processors) which can support up to 100 masterless RTUs.
The system has a capability of handling more than 1000 Inputs and
Outputs, but now, around 140 inputs and outputs (Analog, Digital,
Pulse etc) are energised, which will be expanded later. The system
has two Engineering stations & four Operator stations at
present. It has an Ethernet Data high way operating at 10 mbps. The
Input /Output units are interconnected through the highly popular
PROFIBUS. The MODBUS module is also incorporated in the system so
that dedicated jobs can be done. All these will provide a better
understanding of industrial buses. The laboratory has PLCs and
drives, so as to enhance the range of systems available for
training.
The
Software
The
complete engineering and SCADA development is through a single
software running on Windows. The software has unlimited tags,
trends, graphical displays and has a built in Sequence - of - Events
recording (SOE), which is very essential for fault diagnosis. The
software also has the Dynamic Data Exchange module, which enables it
to import and export data with other application software. The SCADA
Software will be linked with EMS softwares so that the system is
more versatile.
Field
Instruments
The
laboratory has a variety of field instruments and transducers,
including Hall effect, smart and conventional types to measure
temperature, level, voltage, current, frequency, phase angle etc.
The laboratory also has a power analyser, stepper motors, RTDs and
thermisters. A 3-phase 800 KV Transmission line model (scaled down),
complete with circuit breakers & relays add to the better
understanding of SCADA. The Laboratory also receives on-line data
from the 11KV substation supplying the Faculty of Engineering. |
